Telomeres are structures are made up of DNA and protein and act as protective caps on the ends of chromosomes, and influence how quickly cells age. The shorter the telomeres become over time; the faster the cells deteriorate. The findings, to be presented at the Australian Society for Medical Research National Conference, found ultra-marathon runners clocking up 40-100 km a week had 11 per cent longer telomeres.
"This 11 per cent difference adds 16 years to your life expectancy," Prof Charchar said.
So not only does it make you feel better, it could be adding years to your life!
